To all 4071 m it may concern Be it known that I, MARTIN FEYBUscH, a citizen of Germany, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in F langing-Machines for Containers, of which the following is a specification.

This invention relates to a machine of novel construction, for turning the covering sheet or strip of a paper box, sheet metal can or other container, first horizontally over the edge of such container, and then down against the inner side thereof. The machine may be readily adjusted to different sizes and configurations of containers, and is therefore well adapted to operate on small lots. It is distinguished by its great simplicity of construction, one and the same roller being employed during the flanging as well as during the turning in operation, while all grippers and gripper operating means which were heretofore generally employed are entirely dispensed with.

Briefly stated, the machine receives the box or other container with the covering sheet or strip attached, and projecting somewhat above the upper edge thereof. A rollerthen turns the protruding portion of said strip over such edge, by means of a flange and then a former enters the box and forces the turned over portion down against the inner side of the box, while finally, a cylindrical section of said roller presses the turned over portion against said inner side.

In the accompanying drawing: Figure 1 is a side elevation of a fianging machine embodying my invention; Fig. 2, a front elevation; Fig. 3, a section ,on line 3-3 Fig. 1. Fig. 4, a section on line M Fig. 1, and Figs. 5, 6 and 7, show consecutive positions of the former and pressing-roller.

The power shaft 1 which is journaled in the machine frame 2, carries fast and loose pulleys 3, 4 cooperating with a suitable belt shifter 5. Shaft 1 is by wheels 6, 7 intergeared with a counter shaft 8, which by bevel gear 9,' continuously rotates a vertical cam shaft 10. This shaft carries an upper cam 11, a lower cam 12, and a mutilated gear wheel 13, hereinafter more fully described.

Upper cam 11 is engaged by a cam roller 14 carried by one member of a pair of levers 15 that are pivoted to'the machine frame at 16, and are bylinks 17, connected to the cross head 18, of a shaft 19, the configuration of the cam being such that anintermittent reciprocating movement is imparted to the shaft.

' The lower end of shaft 19, carries a core 20 over which the box 21, to be flanged is adapted to be projected. This core the top of which should be somewhat lower than the box, so as to leave an upper empty space therein, is removably secured to the shaft in suitable manner, so that it may be readily replaced by a core of different size and configuration, the drawing showing by way of example, a square core, adapted for flanging of a square box.

Shaft 19 is telescoped by a-tubular shaft 22 above which it projects, and to which it is connected by' a groove and feather 23 in such a manner, as to have independent vertical movement within shaft 22, while participating in the intermittent rotary movement. of the latter. Shaft 22, receivesvertical reciprocating movement from lower cam 12, by a cam roller 21 carried by one member of a pair of levers 25 pivoted to the machine frame at 26, and connected by links 27 to a cross head 28 of shaft 22.

In addition to the vertical movement, shaft. 22 likewise receives an intermittent rotary movement, which movement as has .wheel 13, which is adapted to engage a toothed wheel 29 having an eye through which shaft 22 is free to slide. The operative rim ofwheel 13, has two toothed sections, which are separated by a long plain section, and a short plain section. Set back from the two plain sections are a pair of curved guides 30', 31 which extend upwardly from the upper face of the wheel, and are mounted concentrically with the latter. Guides 30, 31 are .adapted to be engaged by a concaved lug 32, which is attached to wheel 29, by screws 33, and which likewise has an eye through which-shaft 22 is vertically slidable. This'eye, however, is furnished with. a plurality of feathers 34adapted to engage longitudinal surface grooves 35 of the shaft, by which construction, the shaft is free to pass vertically through Wheel 29 and lug 32, while at the same time, receiving intermittent rotary movement from wheel 13.

To the lower end of shaft 22, there is removably secured, a combined guide block and former 36 which corresponds in shape substantially to that of core 20, being of square shape in the embodiment shown. The block is furnished with a circumferential groove 37, and is adapted to be projected with its lower section into the upper empty section of box 21, which is not taken up by core 20.

To the lower end of shaft 10, is fitted, a cam 38 having two salient sections and a pair of receding sections. The cam roller 39, is carried by a lever 40, having a hub 41 and influenced by a spring 42. On lever 40, is mounted, a pawl 43, adapted to engage a toothed segment 44 fast on a shaft 45 on which hub 41 turns. Pawl 43 is drawn toward the segment by a week spring 46 and is adapted to be thrown out of engage ment with the segment by a finger 47 Shaft 45 carries a curved horizontally oscillable arm 48, influenced by aspring 49, and having at its free end, a vertical hub 50, in which is free to turn, a spindle 51. This spindle carries at its upper end, a guide roll 52 adapted to engage block 36, and a lower fianging and pressing roller 53, having a lower cylindrical section adapted to engage the box covering along the rim of box 21, and an upper flange 54 adapted to turn in such covering over such rim. The'correlation of gear wheel 13 and cam 38 is such that when the active or toothed portions of former, rotate shafts 19 and 22, by means of wheel 29, the receding faces of cam 38 will be engaged by roller 39, so as to simultaneously swing the free operative end of arm 48 inward or toward the Work piece by spring 49 during which movement pawl 43 will be thrown out of engagement with toothed segment 46 by finger 47. When however, the mutilated faces of wheel 13' are opposed to wheel 29, and its guides 30,-

' 31'become engaged by lug 32, the protruding faces of 'cam 38 will come into play, in such a way that lever 40 will by pawl 43 and toothed segment 44 swing the free operative end of arm 48 outward or away from the work piece against action of spring 49.

Below shafts l9 and 22, the machine frame is provided with a foot or support 551ming adjustable gages 56 and yieldingly su'pported by a buffer spring 57.

In use, the box, can or other container to be flanged is provided with a previously gummed covering layer or strip 58 that projects a distance above the upper edge of the container.

The container is in the condition described, placed upon support 55, core 20 is by cam 11 and shaft 19, lowered into the box, while block 36 remains raised.' Wheel 13 will now by one of its active sections turn wheel 29, and thus simultaneously ro-' while flange 54 will turn the protruding end or flange 59 of covering 58 horizontally over the rim of the box (Fig. 5). During this operation, the cylindrical portion of roller 53 will engage the unbacked rim of box 21, and be pressed against the same by spring 49 any undue pressure being however, prevented by the engagement of guide roller 52 with block When this operation has been completed, the short mutilated section of wheel 13 will face wheel 29, so that the rotation of the shafts will cease, while block 36-will be lowered by cam 12 and shaft 22 in such a manner that its lower portion will be projected into the vacant upper portion of the box. .In this way, the turned over flange 59 will by the block be pressed into the box and toward the inner face thereof, the spindle 51 with rollers 52, having receded from'the work during this operation (Fig. 6). The second toothed portion of wheel 13 now coming into play, shafts 19 and 22 will resume their rotation, to again turn core 20 and block 36 during which movement arm 48 is again swung inward, so that the cylindrical section of roller 53 will be forced against the rim of the box, as before, while however, its flange 54 will be freely accommodated within groove 37. Inasmuch as block 36 has now however, been withdrawn from guide roller 52, roller 53 will press with the full power-of its spring 49, against the rim of the box, during which operation, the

, lower portion of block 36 will constitute a .bined guide block and former, adapted to be projected into and out of a container, means for folding a covering over the edge of the container, and a guide operatively connected to said folding means and adapted to engage the guide block when the latter is in its raised position. 4
